I have 15 chicks that turned 4 weeks old on Saturday. They are living in their coop that has an attached screened in run. The coop is raised so there is a ramp for them to use to get in and out of the coop. They love to walk up the ramp and spend lots of time sitting on it but they won't go thru the opening into the coop. When it starts to get dark they all huddle together in the corner of the run and we have to pick them up and put them into the coop. When I went out last night they were still walking around and several were sitting at the top of the ramp. I was hopeful that they were finally going to go in on their own so I turned the heat lamp on inside the coop and decided to give them some more time. I'm sure you know what's coming. I totally forgot to go back out and make sure they were inside!! My husband is out of town and after getting the kids to bed I just never thought about the chicks. It hit me this morning as I was getting up and I ran outside in my pj's to check on them. Most of the chicks were still huddled together in the corner of the run but 2 or 3 were already walking around. I live in Wisconsin and the temp got down to about 60 degrees last night and it was pretty damp...luckily it didn't rain. The chicks are all in the coop now where the temp is about 80. Is there anything else I should be doing for them? What signs should I be looking for to see if I've done any damage? Also, why are they not going into the coop at night? All the chicks have been so healthy and happy and until now this has all gone very smoothly. I'll be heartbroken if this makes them all get sick. Thanks for any advice you can give.
